Flourescent Tube Recommendation

[Fishy_7]

I am looking to bid for the following lighting unit:

CLICKY

The adverts states 14K of light, it that necessary good for plany growth? If I were to replace for all 4 tubes, what sould I look for for replacements?

Thanks.

It's the wattage you want to look at for most plant growth, the link has 158watts. To me 14,000K seems very high and I would associate that more with marine tanks than planted freshwater: 6500K is the suggested rating for freshwater planting.

From wikipedia.org:

"Colour temperature
The kelvin is often used in the measure of the colour temperature of light sources. Colour temperature is based upon the principle that a black body radiator emits light whose colour depends on the temperature of the radiator. Black bodies with temperatures below about 4000 K appear reddish whereas those above about 7500 K appear bluish. Colour temperature is important in the fields of image projection and photography where a colour temperature of approximately 5500 K is required to match “daylightâ€￾ film emulsions. In astronomy, the stellar classification of stars and their place on the Hertzsprung-Russell diagram are based, in part, upon their surface temperature. The Sun for instance, has an effective photosphere temperature of 5778 K."

hmmmm .... If I replaced them, what should I replace with for optimal plant growth?

Thanks

There is a link in my sig to a thread I did about the bulbs supplied with these units. If you want to spend a bit more, then there are three options; arcadia plant pros, D&D aquaflora or Hagen life-glo, to be honest I dont know what the general consensus is as to which is best, these tubes are relatively new in the hobby, but I would think all are good, certainly they are by respected manufacturers. You can get them all from Aqiatics-online.co.uk.
